    Studies on Ameliorating Effects of Centella Asiatica on Chronic Cypermethrin Intoxication in Mice
    (Birsa Agricultural University, Ranchi, 1999) N. Muhindro Singh; K. K. Singh
    Despite of the problem of health hazard and environmental pollution posed by their residual effects, it is evident that chemical pesticides will have to be our major means of controlling insects and pests in foreseeable future. Since there is no getting away from pesticides, this experiment is aimed at assessing the ameliorating effects of Centella asiatica on cypermethrin induced chronic toxicity. It is based on the fact that C. asiatica is a safe and consumable herb and is reported to possess antiintoxicant, neuroprotective and hepatoprotective activities. The protective effects of such plants like C. asiatica on low dose pesticide toxicity may emerge as a simple way to get rid of the biological hazards posed by pesticides because these herbs can be taken as diet supplement. However, this required a thorough investigation of the protective effects of this herb in the light of cellular and molecular mechanisms of toxicity of cypermethrin and mode of protection of the plant there on. Keeping these facts in mind, this experiment was carried out on four groups of mice; each consisting of twenty mice. Mice of group-I were given oral drenching of 0.1 ml of distilled water daily which acted as control for other groups of mice while that of group-II were given oral administration of powdered C. asiatica @ 1.25 gm /kg body weight per mice along with oral drenching of 0.1 ml of distilled water. Moreover, mice of group-III were given oral administration of cypermethrin @ 25 mg/kg body weight dissolved in 0.1 ml of distilled water while the mice of group-IV were given oral drenching of cypermethrin @ 25 mg/kg body weight with simultaneous oral

    Studies on Intensity Of Selection On Response and Correlated Response In Mice
    (Birsa Agricultural University, Ranchi, 1999) Sanjay Kumar; .D.K.Mukherjee
    (1) The heritability of litter size at weaning was medium in magnitude while 6-wk. weight and tail length moderate in the base population. Litter size at weaning had negative genetic and phenotypic association with 6-wk. weight and tail length. However, the relationship (genetic and phenotypic) between weight and tail length at 6-wk. was positive and high in magnitude significant. (2) Heritability estimates for 6-wk. weight were moderate to high in magnitude in different line and generation, while were medium to high in magnitude for 6-wk. tail length, indicating scope of further improvement by selection. (3) In selected lines, heritability estimates for weaning litter size were low in magnitude indicating that improvement is possible by exploiting non-additive genetic variance. (4) Negative phenotypic and genetic correlations of weaning litter size with body weight and tail length at 3 and 6-wk. of age, further confirmed negative association between them. (5) The direct response in 6-wk. weight was markedly high with 50% level of selection than that of 75 % level of selection. Whereas observed response in 6-wk. tail length was also high with 50% level of selection. than that of 75 % level of selection for 6-wk. tail lenght.

    Combining Ability And Heterosis Studies In Linseed (Linum sitatissimum L.)
    (Birsa Agricultural University, Ranchi, 1996) Sohan Ram; H.B.P.Trivedi
    Linseed is predominantly a autogamous crop of industrial significance. Inspite of considerable increase in area and production under linseed, the productivity which is of foremost importance, is still stagnant in India. The prime objective of the present investigation was to evaluate some well recognised varieties and explore the combining ability variances of oil yield and seed yield components and their combining ability effects together with the studies on variability, heterosis and correlation through dialled analysis. Eight well recognised varieties of major linseed growing states were obtained from Project Co-ordinator (Linseed), Chandra Shekhar Azad University of Agriculture and Technology, Kanpur. These varieties were crossed in 8 x 8 diallel fashion to obtain 28 direct and 28 reciprocal F1 hybrids. These hybrids were generation advanced in off season nursery to procure F2 seeds. These F1 and F2 hybrids were evaluated separately along with the parents for variability, heterosis, inbreeding depression, combining ability and correlation co-efficient. The analysis of variance was highly significant for oil yield and its components. Variability in the parents and reciprocals, though was non-significant yet was significant in Parents Vs Crosses and F₁ Vs Reciprocals. Manifestation of heterosis was variable in magnitude and nature among corresponding characters in F₁ and F2 hybrids of direct and reciprocal cross. Heterosis as high as 230.90 percent over superior parent was obtained for oil yield in R-7 x Garima, 69,01 percent for oil content in T 397 x R-7 and 202.34 percent for seed yield in Jawahar-23/10 x Garima.Cross Mukta x R-7 was identified as highest heterotic cross for oil yield, seed yield and oil content. CONT Use of parent as pollen or seed parent had a significant difference in heterotic behaviour of the cross. Parents Neelum, Garima and R-17 were identified as best seed parents against R-7 and Jawahar-23/10 as pollen parents. Estimates of GCA and SCA variances obtained were highly significant for oil yield and its components, Non-additive components played major role in expression of oil yield, oil content and seed yield where as other characters exhibited importance of additive component in their expression. The general combining ability effects corresponded fairly with that of per se performance of the parents for all characters except oil content, number of capsules and number of secondary branches per plant. For oil yield, oil content and seed yield though none of the parent was best / good general combiner, yet best / good specific combinations for these traits were obtained from poor x poor combiners. It was noticed that high specific combinations for oil yield were also high specific combinations for seed yield but all high specific combinations for oil content and seed yield components were not necessarily high specific combinations for oil yield. Genotypic correlation co-efficient was higher than phenotypic. Correlation Oil yield was favorably associated with oil content, seed yield, number of capsules and number of secondary branches. Selection of these characters was suggested to increase oil yield.

    Genetic Architecture of pre - wearing growth and survivability of black Bengal and its half- bred kids
    (Birsa Agricultural University, Ranchi, 1999) Saroj kumar; Dk.Singh 'Dron'
    Following conclusions were drawn on the basis of the present findings: Higher pre-weaning growth, survivability of Jamunapari and Beetal halfbreds than purebred Black Bengal revealed that the Jamunapari and Beetal bucks could be utilized as improver for evolving a potential and adaptable breed of goats for meat production. Non-significant effects of sires on absolute weaning weight, relative growth rate in weight during 0-12 weeks of age and survivability of kids during 0 90 days of age indicate that the sire's selection or ranking will be of little importance for altering pre-weaning growth and survivability. However, male kids born as twins of comparatively high milk yielder does should be selected on the basis of body weights at birth, 3 and 6-month of age for breeding purpose.

    Hygienic Quality of Dresses Chicken Meat special Reference to Escherichia coli
    (Birsa Agricultural University, Ranchi, 1999) Shilendra Kumar Sinha; Rejendra Yadav
    In India, the broiler meat is considered to be the meat of choice due to, its short production period, low initial investment and its relatively lower price. Commercial organization engaged in preparing ready to cook poultry and those engaged in export of raw broiler meat must maintain strict microbiological standards to ensure consumer safety and protection from spoilage. Unfortunately such food safety norms and programmes are still not adhered to in our country and there are a lot of roadside shops selling contaminated and unhygienic broiler meat. Therefore the present study was undertaken with the objective of assessing hygienic quality and presence of food borne pathogens i.e. E. coli. Altogether 50 (fifty) samples of broiler meat from 3 sources i.e. Ratu Road Market, Kadru Market and a Private Poultry Farm at Kanke were analysed for bacteriological quality. The samples of Ratu Road Market yielded TVC ranging from 7.8808 to 8.3010 with an average of 8.1003, Fourteen out of fifteen samples were positive for coliform and count varied from zero to 4.0414 with an average of 3.6873. All the fifteen samples were positive for faecal streptococci and the counts ranged from 3.0 to 3.3617 with an average of 3.2001. The samples from Kadru Market yielded TVC ranging from 7.6002 to 8.3979 with an average of 7.9732. Twelve out of 15 samples

    Genetic Studies on Some Economic Traits With Special Reference To Effect Of Inbreeding In Pigs
    (Birsa Agricultural University, Ranchi, 1999) Sanjeev Kumar; K.Singh
    1 Genetic group had significant influence on all the growth and reproductive traits. 2. Exotic pigs are superior with respect to growth and reproductive traits followed by crossbreds and Desi. 3 Among exotics, Landrace performed better than Tamworth. 4. There was progressive improvement in the performance of growth and reproductive traits with the increase of exotic inheritance but just opposite trend was observed with respect to age at first farrowing. 5 Growth rate of suckling piglets during pre-weaning period decreased with the increase of litter size at birth of dam 6 There was a significant increase in pre-weaning growth rate with increase of their birth weight. Similarly post-weaning growth rate increased progressively with the increase of their weight at the time of weaning 7 Lower rate of growth just after weaning in almost all the genetic groups suggested need of special care and management at that stage. 8 Inbreeding adversely affected all the traits under study viz. decrease growth rate and reproductive performance and increase mortality rate svoided as far as possible

    Pharmacokinetics Of Diminazene aceturate In Buffalo Calves
    (Birsa Agricultural University, Ranchi, 1999) Hemant Kumar Panday; B.K.Roy
    . The mean free CSmax (26.28±0.067 ug/ml) of DMZ was evidenced at 5 min declined slowly and CSther was maintained till 48 hr. after single i.v. dose (8mg/kg) administration in buffalo calves.. 2. It was evidenced that DMZ was rapidly absorbed after i.m. administration with a tmax at 30 min. 3. The mean peak free serum concentration (8.41±2.43 µg/ml) of DMZ was obtained at tmax of 30 min. after single i.m. dose (16mg/kg) administration. 4. The overall serum concentration of DMZ obtained after single i.m. injection was lower than its single dose i.v. administration. 5. The possible reason for attainment of lower DMZ serum concentration after i.m. administration has been explained with the help of results obtained for kinetic variables. 6. The Cumax of DMZ was observed at 1 hr. (240.00+1.77 µg/ml) and 3 hr. (286.25 +4.10µg/ml) after single dose i.v. and i.m. administration respectively. 7. Urinary excretion of DMZ was dependent on the amount of drug available in systemic circulation which indicated that this compound followed first-order elimination kinetics in buffalo calves.

    (Birsa Agricultural University, Ranchi, 1999) Tayyaba Arfa; S.Haque
    The study on gastroenteritis in pups was conducted with special reference to parvoviral infection in the department of Medicine, Ranchi Veterinary College, Ranchi from May, 1998 to August 1999. The salient features of investigation were summarized as follows: Studies were conducted to confirm the existence of CPV infections among dogs in Ranchi by Agar Gel Immuno-Diffusion Test (AGIDT). Experimental studies were made to observe the symptoms and to record the hematological, biochemical and histopathological changes in CPV infected pups. Altogether 127 dogs of different breeds such as German Shepherd (52), Pomeranian (30); Doberman Pinscher (16); Labrador (4), Dachshund (8); Great-Dane (2); Dalmatian (5); German Spitz (2); others (8) including cross bred, St. Bernard, Rottweiler, showing the symptoms of haemorrhagic gastroenteritis were tested by AGIDT and 67 (52.76 %) animals were found positive for canine parvovirus infection, 38 (29.92 %) cases of gastroenteritis were due to different parasites and 22 (17.32 %) were due to bacterial infection. The disease occurred in almost all breeds of dog and no variation was observed in respect of sex. However it was observed that in Pomeranian the disease was very severe. Majority of cases occurred in young dogs below six months of age. However adult dogs were also affected with this disease. In the present study incidence of disease was maximum in winter and lowest in summer.

    (Birsa Agricultural University, Ranchi, 1999) Prabhat kumar Singh; D.K.Thakur
    The work on "management of anemia during treatment of theileria infection in cattle" was carried out in Dept. of Veterinary Medicine, Ranchi Veterinary College. (BAU), Kanke, for a period of two years from 1997 to 1999. A total of 263 febrile animals were examined, out of which 64 animals (24.33%) were found positive for theileria infection. In present observation the maximum age of positive animals was 6 years and minimum age of positive calf was 13 days. There was progressive increase in the incidence of tropical bovine theileriasis with the increase of age, the highest incidence was in the age group of 3 yrs and above (32.19%). During investigation it was observed that the maximum incidence of disease was in July (41.6%) and lowest in the month of January and May (0%). In general the disease was seen in June to November. There was distinct decrease of hemoglobin, packed cell volume. T.L.C., T.E.C. and D.L.C. due to theileria infection of varying degree but after treatment hemoglobin, packed cell volume. T.L.C., T.E.C. and D.L.C. reached towards normal value. Clinical symptoms observed in theileria cases were continuous fever. In some cases intermittent fever, enlarged superficial lymph node, jaundice, reduced milk yield, anaemia, accelerated pulse rate and respiration. All theileria positive cases were treated with specific treatment "Butalex" (Buparvaquone) by intramuscular route (Single dose) at the dose rate of 2.5 mg/kg body weight, and to overcome anemic condition, out of three regimen. of treatment. Imferon + Liv. ext. with B. Complex treatment was found. Satisfactory to overcome anemic condition. In severe cases of anaemia blood transfusion was the only way to save the life of animal.
